Chemical Structure
Description
CATO supplies 6-(4-Bromophenyl)-2-chloro-4-methylnicotinonitrile (CAS 1956331-61-5), a certified reference material (molecular formula C13H8BrClN2, MW 307.57 g/mol) for analytical method development and quality control.
Structurally, 6-(4-Bromophenyl)-2-chloro-4-methylnicotinonitrile (C13H8BrClN2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 307.57 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
